We do prevent people from driving a car at all until they pass a test proving that they can do so competently, and even then they typically have strong restrictions on what they can do while driving for several years to help further reduce the risk they can pose. Perhaps a fair comparison would be if we required those who do not wish to get vaccinated to have a relevant medical degree to prove that they know what they're doing?
